In 1994 David Chalmers published a paper explaining why consciousness is such a challenging phenomenon to understand. Although he wasnât the first to discuss these challenges, he was the first to categorize them into two types of problems: âeasyâ problems and the âhardâ problem.
Rotator cuff tear arthropathy (or shoulder arthritis with a large rotator cuff tear) is a severe and complex form of shoulder arthritis in which the shoulder has lost not only the cartilage that normally covers its joint surface but also the tendons of the rotator cuff tear which help position and power the joint.enetics. Rotator cuff tear arthropathy (or shoulder arthritis with a large rotator cuff tear) is not known to be inherited although rotator cuff tears appear to be more common in individuals from families in which other members also have cuff tears.
Rotator Cuff Tears. Also Known as: Tendon Tear, supraspinatus tendon tear. The rotator cuff is a group of tendons that connects the four muscles of the upper shoulder to the bones ( see Anatomy ). The strength of the cuff allows the muscles to lift and rotate the humerus (the bone of the upper arm). The tendons run under the acromion (part of the shoulder blade) where they are very vulnerable to being damaged. This can lead to a tear resulting in a painful, weak shoulder.
